Abstract

The invention discloses an under-pressure fluid-guiding sealing device for emergency repair of a pipe. The under-pressure fluid-guiding sealing device for the emergency repair of the pipe comprises a closed fluid-guiding box, a U-shaped supporting bracket and a pipe injection-pressing reinforcing plate. The under-pressure fluid-guiding sealing device for the emergency repair of the pipe is characterized in that: the closed fluid-guiding box is fixed on a leaking pipe through the U-shaped supporting bracket and the pipe injection-pressing reinforcing plate; a fluid-guiding pipe is arranged on the closed fluid-guiding box and a fluid-guiding valve is arranged on the fluid-guiding pipe; fixing holes which are matched with the U-shaped supporting bracket are arranged on the pipe injection-pressing reinforcing plate and are fixed through fastening screw nuts; and the fluid-guiding sealing device is fastened on a water-leaking area under the action of an injection-pressing structure, and the water-leaking area is depressurized to a weldable state by guiding fluid under the action of fluid-guiding through the reinforcing measures of welding and fluid-guiding, so that the sealing can be completed. The under-pressure fluid-guiding sealing device is suitable for the emergency repair and sealing of steel pipes, cast iron pipes, glass fiber reinforced plastic pipes, concrete pipes and the like, and is the device for enabling the pipes to re-reach a sealing state without lowering the dynamic pressure of a medium.

Description

A kind of pipe first-aid band is pressed the drainage sealer
Technical field
The invention belongs to the pipe-line system field, particularly a kind of pipe first-aid band is pressed the drainage sealer.
Background technique
China pressure line engineering branch is extremely wide, and pipeline is the main body of engineering.From using the percolating water angle relatively, China's pipeline is because steel pipe is subjected to corrosion in various degree, the corrosion of prestressed reinforcement in the concrete pipe, the reason such as aging of other pipe, about just finding have 50% in about 20 years, use has percolating water hidden danger, serious threat is to the safe operation of pipeline, and operation management unit can often face the repairing task.In a single day the pressure of supply water pipeline leaks in process of production, be difficult under the dynamic condition and rush to repair.The bigger situation of pressure medium particularly, general all is after closing control valve up and down and letting out water in the end conduit, carry out pipeline and pipe fitting displacement maintenance, to damage pipeline originally and remove, and adopt equipment such as crane lifting, screw jack to push up near the installation with bellmouth that has flexible interface and socket, after two ends install, do temporary fixed with portal frame and chain sling, after above-mentioned work is finished, intervalve with crane lifting in the middle of steel joint socket up and down, finishing soldering opening can water flowing.This processing method is consuming time many; expense is high and have influence on ordinary production; if the external environment condition of pipeline maintenance is relatively poor; as externally drained difficulty; repairing machinery (as excavator, crane etc.) enters difficulty; then rushing to repair cost can be bigger; repairing efficient is lower; and need certain hour to stop to supply water and the pipeline operation; through regular meeting the evaporating, emitting, dripping or leaking of liquid or gas phenomenon appears for quantity-produced city common-use tunnel, enterprise etc.; if adopt the stop production to overhaul leak stopping, under water supply fraction standard-required condition with higher, be worthless.The method of advanced technology such as some perfusion sealing compounds, bigger to the mass of medium influence, under the situation of medium operation, be difficult to operation, and cost is very high.The basic ideas that band presses the drainage sealer to use are to be discharged into beyond the setting with the medium drainage in the pipeline and with flexible pipe with closing envelope water conservancy diversion box, under the situation that reduces pipeline internal medium pressure, adopt welding procedure, P shape rubber pad sealing, finish in welding and fastening semi-circular fastener, if the breakthrough that pressure parts walls such as pipeline or flange plate produce because of crackle, press the seepage flow sealing might not control the expansion in crack based on considering band, in this case, build the high grade steel concrete, generally will be more than 500#.After steel concrete reached certain length of time, the throttle down normal water supply if water supply time is urgent, can not be built steel concrete and directly close valve supply water.Finish the airtight leak-stopping at percolating water position under the situation that this treatment technology can keep ordinary production, operation to continue, avoided the loss that stops production of stopping, the economic attrition of releasing system medium.Overall merit, workable, environmental protection, safety, rapidly, economy and social benefit be very high.
Summary of the invention
Technical assignment of the present invention is to provide a kind of pipe first-aid band to press the drainage sealer at above the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pipe first-aid band is pressed the drainage sealer, comprise airtight water conservancy diversion box, U-shaped supporting frame and pipeline roof pressure gusset plate, wherein, described airtight water conservancy diversion box is fixed on by U-shaped supporting frame and pipeline roof pressure gusset plate and reveals on the pipeline, described airtight water conservancy diversion box is provided with honeycomb duct, and be provided with guide valve on honeycomb duct, described pipeline roof pressure gusset plate is provided with the fixed hole that matches with the U-shaped supporting frame, and fixes by tightening nut.
The neutral position is provided with the roof pressure screw rod on the described pipeline roof pressure gusset plate, is connected with the roof pressure piece at an end of roof pressure screw rod.
Described airtight water conservancy diversion box is welded with stiffening plate with leakage pipeline connecting part.
The present invention has following beneficial effect:
1, reasonable in design, simple in structure, easy to use;
2, do not reducing under the medium dynamic pressure condition, making the leakage pipeline reach airtight again.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description the present invention is done following detailed explanation.
As shown in the figure, a kind of pipe first-aid band is pressed the drainage sealer, comprise airtight water conservancy diversion box 2, U-shaped supporting frame 1 and pipeline roof pressure gusset plate 3, wherein, described airtight water conservancy diversion box 2 is fixed on by U-shaped supporting frame 1 and pipeline roof pressure gusset plate 3 and reveals on the pipeline 10, and described airtight water conservancy diversion box 2 is provided with honeycomb duct 4, and is provided with guide valve 5 on honeycomb duct 4, described pipeline roof pressure gusset plate 3 is provided with the fixed hole that matches with U-shaped supporting frame 1, and fixing by tightening nut 8.
The neutral position is provided with roof pressure screw rod 6 on the described pipeline roof pressure gusset plate 3, is connected with roof pressure piece 7 at an end of roof pressure screw rod 6.
Described airtight water conservancy diversion box 2 is welded with stiffening plate 9 with leakage pipeline 10 connecting parts.
